[0021] This specific embodiment is a relief three-dimensional pattern environmentally friendly paint wall cloth and its production process, and its structural diagram is as follows Figure 1-10 As shown, it includes: a bottom layer 1, which is made of fiber material. The flexibility of the fiber material allows the wall cloth to deform moderately along with a certain curvature or slight unevenness of the wall during the pasting process without being easily broken. The strength ensures that the overall structure of the wall cloth can bear a certain weight and external force without being easily damaged. The good stability can provide solid support for the basic structure of the wall cloth, so that other structures and decorations on the wall cloth can exist stably. At the same time, the fiber material may also have some characteristics such as certain moisture-proof and antibacterial properties, which help to protect the internal structure of the wall cloth from excessive influence of environmental factors. A connecting structure 2 is provided on both sides of the center of the upper end surface of the bottom layer 1.

[0022] First, in this embodiment, the specific structure of the connection structure 2 is as follows: The two connecting structures 2 include two grooves 203, which are respectively arranged at the center of the upper end surface of the bottom layer 1. Slide grooves 201 are provided at the front and rear centers of the two inner side walls of the two grooves 203. Pasting racks 204 are provided at the inner centers of the two grooves 203. Sliders 202 are provided at the front and rear centers of the two side walls of the two pasting racks 204. Pasting grooves 205 are provided at the centers of the upper end surfaces of the two pasting racks 204. The first adhesive 206 is provided at the inner centers of the two pasting grooves 205. Pins 207 are provided at the front and rear ends of the upper ends of the two side walls of the bottom layer 1. One end portion of the four pins 207 respectively penetrates through the two side walls of the bottom layer 1, the one side wall of the two grooves 203 and the one side wall of the two pasting racks 204 in sequence and passes into the interior of the two pasting racks 204. An intermediate layer 3 is provided at the center of the upper end surface of the bottom layer 1.

[0023] Through the slide 201 and the slider 202, the pasting frame 204 can slide along the slide 201 in the groove 203, realizing the flexible relative movement of the pasting frame 204 relative to the groove 203, providing convenient conditions for subsequent installation or disassembly operations, and at the same time, it can also better position the pasting frame 204 in the groove 203. The bottom is fixed in the position of the pasting frame 204 in the groove 203 through the latch 207. When the latch 207 is inserted, the displacement of the pasting frame 204 in the groove 203 is limited, ensuring the stability of the connection structure 2, so that the bottom layer 1 and the relevant components are firmly connected. The first adhesive 206 is provided in the center of the pasting groove 205 set at the center of the upper end surface of the pasting frame 204 for pasting the middle layer 3. The viscosity of the first adhesive 206 enhances the reliability of the connection and prevents loosening between components. The fiber material has certain flexibility, strength and stability.

[0024] The material of the middle layer 3 is wood pulp. The middle layer 3 made of wood pulp has certain adsorption and cushioning properties and a certain strength. The adsorption property can help absorb some moisture, odor, etc. that may penetrate into the wall cloth. The cushioning property can play a buffering role when the bottom layer 1 is impacted by external force, reducing the impact on the upper structure. The strength of the middle layer 3 can be combined with the bottom layer 1 to jointly maintain the overall structural stability of the wall cloth. In addition, the wood pulp material may also have a certain impact on the texture, touch, etc. of the wall cloth to a certain extent, making it more natural and soft.

[0025] A mounting structure 4 is provided at the center of the upper end surface of the middle layer 3, and the mounting structure 4 includes a protective frame 403. A protective frame 403 is provided at the center of the upper end surface of the middle layer 3, and a card block 402 is provided at the center of the lower end surface of the protective frame 403. A card slot 401 is provided at the outer side of the center of the upper end surface of the middle layer 3, and a second adhesive 404 is provided at the center inside the card slot 401. A composite layer 406 is provided at the lower center inside the protective frame 403, and a non-woven fabric 405 is provided at the center of the upper end surface of the composite layer 406. A composite layer 406 is provided at the center of the upper end surface of the non-woven fabric 405. The card slot 401 and the card block 402 are adapted to each other. Positioning grooves 8 are provided at the four diagonals of the upper end surface of the composite layer 406, and a carving layer 5 is provided at the center of the upper end surface of the composite layer 406. The material of the middle layer 3 is wood pulp, and a carving groove 6 is provided at the center of the upper end surface of the carving layer 5, and positioning columns 7 are provided at the four diagonals of the lower end surface of the carving layer 5.

[0026] The four positioning posts 7 are respectively adapted to the four positioning grooves 8, and the card slots 401 and the card blocks 402 are adapted to each other. This locking structure facilitates the installation and positioning of the protective frame 403 on the middle layer 3. During installation, it is only necessary to align the card blocks 402 with the card slots 401 and snap them in. The protective frame 403 can be installed quickly and accurately, and can limit the shaking and displacement of the protective frame 403 on the middle layer 3 to a certain extent, ensuring the stable installation of the protective frame 403. The second adhesive 404 is set at the center of the card slot 401. After the card block 402 is snapped into the card slot 401, the second adhesive 404 can be further The connection strength between the card block 402 and the card slot 401 is further enhanced to prevent the card block 402 from accidentally falling out of the card slot 401, thereby improving the stability and durability of the entire installation structure 4 and ensuring that the protective frame 403 is always firmly installed on the middle layer 3. The non-woven fabric 405 can play a role in buffering, filtering and adsorption, and can buffer the impact of the outside world on the internal structure of the wall cloth, thereby avoiding direct contact of some impurities and dust with the internal structure of the wall cloth. The composite layer 406 can improve the relevant performance of the wall cloth in many aspects, enhance the strength and stability of the wall cloth, and may also have certain sound insulation, heat insulation, moisture-proof and other functions.

[0027] By adapting the four positioning posts 7 to the four positioning grooves 8 respectively, the cooperation between the positioning posts 7 and the positioning grooves 8 can quickly and accurately locate the position of the engraving layer 5 on the composite layer 406 during the production or installation of the wall cloth, ensuring the accuracy and stability of the installation of the engraving layer 5, so that the engraving layer 5 can be accurately located at the required position of the wall cloth to play its decorative and other functions. At the same time, the cooperation between the positioning posts 7 and the positioning grooves 8 also helps to align and fit the layers during the production of the multi-layer wall cloth, ensuring the regularity of the overall structure of the wall cloth.

[0028] When the device of the present technical solution is used, a sliding connection structure 2 is formed by the slide groove 201 on the inner wall of the groove 203 and the sliders 202 on both sides of the pasting frame 204. When installing or removing related parts, the pasting frame 204 can slide smoothly along the slide groove 201 in the groove 203, which is convenient for adjusting the position or replacing the pasting frame 204. This sliding design makes the wall cloth more flexible during assembly and can adapt to different wall conditions and installation requirements. The pin 207 on the side wall of the bottom layer 1 passes through the bottom layer 1, the groove 203 and the pasting frame 204, and plays the role of locking the pasting frame 204 in the groove 203. After installation, the inserted pin 207 can prevent the pasting frame 204 from sliding or shaking in the groove 203, ensuring the stability of the connecting structure 2, making the bottom layer 1 firmly connected to other layers, and avoiding the relative displacement between the layers of wall cloth affecting the overall structure and appearance. The pasting groove 205 at the upper end of the pasting frame 204 and the first adhesive 206 inside are used to enhance the connection strength between components. During the installation process, the pasting structure can fit tightly with the middle layer 3 or other adjacent components. Through the viscosity of the first adhesive 206, it can effectively prevent loosening or separation between components, thereby improving the integrity and stability of the wall cloth structure.

[0029] The card slot 401 on the middle layer 3 and the card block 402 at the lower end of the protective frame 403 are adapted to each other to form a card connection. When the wall cloth is assembled, the card block 402 is accurately inserted into the card slot 401, and the protective frame 403 can be quickly positioned and installed, ensuring that the position of the protective frame 403 on the middle layer 3 is accurate, and effectively limiting the displacement of the protective frame 403 in the horizontal and vertical directions, enhancing the stability and reliability of the installation structure 4. The second adhesive 404 in the card slot 401 takes effect after the card block 402 is inserted. It can not only fill the small gap between the card block 402 and the card slot 401, but also further enhance the bonding force between the two, preventing the card block 402 from falling out of the card slot 401 due to external vibrations, collisions and other factors, ensuring that the protective frame 403 is always firmly installed on the middle layer 3, and protecting the integrity of the wall cloth structure.

[0030] The non-woven fabric 405 and the composite layer 406 inside the protective frame 403 jointly provide a variety of protective properties. The non-woven fabric 405 has the characteristics of breathability, moisture absorption, and filtering. It can adjust the humidity environment inside the wall cloth to prevent water vapor accumulation from causing mold on the wall or degumming of the wall cloth. At the same time, it can also filter dust and impurities in the air to protect the internal structure of the wall cloth from pollution. The composite layer 406 enhances the strength of the wall cloth, improves its wear resistance and tear resistance, and improves the overall quality and service life of the wall cloth, making it less likely to be damaged during long-term use and maintaining a good decorative effect.

[0031] The positioning column 7 at the lower end of the carving layer 5 and the positioning groove 8 at the upper end of the composite layer 406 are adapted to each other. During the production or installation of the wall cloth, the positioning column 7 and the positioning groove 8 can accurately align the positions of the carving layer 5 and the composite layer 406, ensuring that the carving layer 5 is accurately installed on the composite layer 406. This not only helps to maintain the neat structure between the layers of the wall cloth, but also ensures that the relief pattern on the carving layer 5 is accurately aligned with the overall design of the wall cloth, thereby enhancing the decorative effect of the wall cloth and making the relief three-dimensional pattern more beautiful, natural and coordinated. The bottom layer 1 is made of fiber material. The good flexibility of the fiber material enables it to adapt to the slight unevenness of the wall surface and a certain degree of bending and deformation. It is not easy to break due to irregularities of the wall surface during the posting process. It has a certain strength and can provide stable support for the wall cloth, bear the weight of the various layers of the wall cloth and the external force impact in daily use, and protect the integrity of the internal structure of the wall cloth.

[0032] The moisture-proof and antibacterial properties that the fiber material may have can help prevent the wall from mildewing caused by a humid environment, extend the service life of the wall cloth, and maintain the health and hygiene of the wall cloth. The middle layer 3 is made of wood pulp, which has adsorption properties and can absorb odors or small amounts of water vapor that may be generated inside the wall cloth, reduce odors in the indoor air, and improve indoor air quality. Its moderate buffering performance can reduce the transmission of impact force to the upper structure when the bottom layer 1 is impacted by the outside world, protect structures such as the carved layer 5 and the protective frame 403 from damage, and enhance the impact resistance of the wall cloth. In addition, the selection of wood pulp material may also affect the texture of the wall cloth, making it softer and more natural to the touch, thereby enhancing the user's tactile experience. Example

[0033] Based on Example 1, Figure 1-10 As shown, the present invention provides a process for producing an environmentally friendly painted wall covering with a relief three-dimensional pattern, comprising the following steps: S1.

In addition, apply the first adhesive 206 at the center of the upper end surface of the adhesive frame 204, and fix the adhesive frame 204 in the groove 203 by using the pin 207 to ensure that its position is accurate and firm.

[0036] S4. The prepared wood pulp slurry is evenly coated on the upper surface of the bottom layer 1, and the wood pulp layer is dried by a drying device to solidify it and form an intermediate layer 3. The intermediate layer 3 is surface treated, such as polishing and cleaning, to improve its adhesion to the upper structure. A protective frame 403 is installed at the center of the upper end face of the intermediate layer 3 to ensure that the block 402 and the card slot 401 fit well. A composite layer 406 is installed at the lower center of the inner part of the protective frame 403, and a second adhesive 404 is coated on its upper end face. The non-woven fabric 405 is pasted on the composite layer 406 to ensure that it is flat and free of bubbles.

[0037] S5. According to the design requirements, use an engraving machine to carve the required relief pattern on the engraving layer 5, and perform surface treatment on the engraving layer 5, such as polishing and coloring, to improve its aesthetics and durability. Install positioning posts 7 at the four diagonal corners of the lower end surface of the engraving layer 5, ensuring that the height and position of the positioning posts 7 are accurate to ensure that they cooperate well with the positioning grooves 8. Ensure that the position of the engraving layer 5 is accurate and firm by aligning the positioning posts 7 of the engraving layer 5 with the positioning grooves 8 of the composite layer 406, and make necessary adjustments.

[0038] S6.

Surface treat the non-woven fabrics to improve their adhesion to the composite layer. Select environmentally friendly adhesives, such as water-based acrylic adhesives, to ensure they are non-toxic, odorless, and have high bonding strength. Prepare the appropriate amount of adhesive according to product requirements and conduct quality inspections. S2. The pretreated fiber material is fed into a loom to weave a fiber cloth having a certain density and thickness, the fiber cloth is heat-set to stabilize its shape and size, and surface treatments such as polishing and cleaning are performed to improve its adhesion to the adhesive; S3. Two grooves 203 are formed at the center of the upper end surface of the fiber cloth using a mold. A slide groove 201 is machined at the center of the inner wall of the groove 203. An adhesive frame 204 is installed inside the groove 203 to ensure that the slider 202 and the slide groove 201 fit well together. A first adhesive 206 is applied to the center of the upper end surface of the adhesive frame 204. The adhesive frame 204 is fixed in the groove 203 using a latch 207 to ensure that it is accurately and securely positioned. S4. The prepared wood pulp slurry is evenly applied to the upper surface of the bottom layer 1, and the wood pulp layer is dried by a drying device to solidify and form an intermediate layer 3. The intermediate layer 3 is surface treated, such as polishing and cleaning, to improve its adhesion to the upper structure. A protective frame 403 is installed at the center of the upper end surface of the intermediate layer 3, ensuring that the block 402 and the slot 401 fit well together. A composite layer 406 is installed at the lower center of the protective frame 403, and a second adhesive 404 is applied to its upper end surface. The non-woven fabric 405 is adhered to the composite layer 406, ensuring that it is flat and free of bubbles. S5. Use an engraving machine to carve the desired relief pattern on the engraving layer 5 according to the design requirements. Perform surface treatment on the engraving layer 5, such as polishing and coloring, to improve its aesthetics and durability. Install positioning posts 7 at the four diagonal corners of the lower end surface of the engraving layer 5. Ensure that the height and position of the positioning posts 7 are accurate to ensure that they fit well with the positioning grooves 8. Ensure that the engraving layer 5 is accurately and securely positioned by aligning the positioning posts 7 of the engraving layer 5 with the positioning grooves 8 of the composite layer 406. Make any necessary adjustments. S6. Assemble the middle layer 3 with the bottom layer 1 to ensure the firmness of the connection structure 2, assemble the protective frame 403 and the composite layer 406 with the middle layer 3 to ensure that the block 402 and the slot 401 fit well, assemble the engraving layer 5 with the composite layer 406 to ensure that the positioning column 7 and the positioning slot 8 fit well, evenly apply an appropriate amount of adhesive on the contact surface of each layer structure to ensure that the adhesive is evenly applied without omission to ensure the bonding strength between the layers, and perform an appearance inspection on the assembled wall cloth to ensure that there are no flaws or defects.
